(AP) -- A water main break at NASA's spaceport has launch preparations on hold for the next-to-last shuttle flight.
Space shuttle Discovery was supposed to be moved Wednesday from the hangar to the giant Vehicle Assembly Building at Kennedy Space Center in Florida. That's where the fuel tank and booster rockets are attached to a shuttle.
But the water main break forced NASA to close the space center to most personnel. And Discovery's short trip from one building to another was delayed until at least Thursday.
Discovery is supposed to blast off Nov. 1 with supplies for the International Space Station. NASA says Wednesday's trouble will not affect the launch date. Endeavour will follow in February to close out the shuttle program.
